A brief introduction to composite materials

What is a composite material?
A composite material is an engineering material, often referred to as a composite, made of at least two or more materials with significantly different physical and chemical properties, including a substrate that acts as a bond and a reinforcement that acts as a force. At the macro level, composite products can maintain and embody the different properties of their constituent materials.
According to the different substrates, composite materials can be divided into polymer base composite, metal base composite, and ceramic base composite three categories:
PMC\’s, that is, polymer-based composites, is a typical composite material, usually referring to FRP, that is, fiber-reinforced plastics. FRP is made of thermosetting or thermoplastic resin as the matrix, with short or continuous fiber and its fabric as the reinforcement phase, by composite. Common reinforcements include glass fiber, carbon fiber, and Kevlar (aramid fiber).
MMCs \’s, or metal-based composites, are increasingly used in the automotive industry, where the base material is a metal, such as aluminum, and the reinforcement is usually silicon carbide.
CMC\’s, that is, ceramic-based composites, commonly used in high-temperature environments, the substrate is ceramic, and the reinforcement is short fiber, silicon carbide, or boron nitride.
